1 . ManageController .java

package com.want.address.controller;

import java.net.URLEncoder;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.want.address.mo.UserContext;
import com.want.address.threadlocal.UserThreadLocal;

/**
*
* @author 00301957
*当前登录人跳转controller
*/
@Controller
public class ManageController {

@RequestMapping(value="manage")
public ModelAndView testLogin(HttpServletResponse response) throws Exception{
ModelAndView modelAndView = new ModelAndView("manage");
// 获取当前登录人员信息
UserContext userContext = UserThreadLocal.get();

//生成16位随机字符串
// String string = "qwertyuiopasdfghjklzxcvbnmQAZWSXEDCRFVTGBYHNUJMIKOLP";
// StringBuffer sb = new StringBuffer();
// int len = string.length();
// for (int i=0; i<16; i++) {
// sb.append(string.charAt((int)Math.round(Math.random()*(len-1))));ssss// }
// String keyStr = sb.toString();
// String plainText = userContext.getAccount();

//加密工号
// String encUserCode = CryptAES.AES_Encrypt(keyStr, plainText);

modelAndView.addObject("key", userContext.getAccount());

//设置cookie
Cookie cookie = new Cookie("encUserCode", URLEncoder.encode("encUserCode", "UTF-8"));
cookie.setDomain("want-want.com");
cookie.setPath("/");
response.addCookie(cookie);
return modelAndView;
}

}

2. UserThreadLocal.java

package com.want.address.threadlocal;
import com.want.address.mo.UserContext;

public class UserThreadLocal {
private static final ThreadLocal<UserContext> USER = new ThreadLocal<UserContext>();
public static void set(UserContext userContext) {
USER.set(userContext);
}
public static UserContext get() {
return USER.get();
}
public static void clear() {
set(null);
}
}

3. UserContext .java

package com.want.address.mo;
public class UserContext {
public static final String USER_CONTEXT_KEY = "discussUserContext";
private String account;
private String userName;
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}

4. 过滤器UserContextHandlerInterceptor .java

package com.want.address.intercepter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import com.sap.security.api.IUser;
import com.sap.security.api.UMFactory;
import com.want.address.mo.UserContext;
import com.want.address.threadlocal.UserThreadLocal;

public class UserContextHandlerInterceptor extends HandlerInterceptorAdapter {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
HttpSession session = request.getSession();
UserContext userContext = (UserContext) session.getAttribute(UserContext.USER_CONTEXT_KEY);

// 判断session中有没有记录当前登录人员的信息
if (userContext == null) {
// 创建空的 UserContext
userContext = new UserContext();
// 未登录清空ThreadLocal中的数据
UserThreadLocal.clear();
// 取得当前登录人员对应的account
IUser user = UMFactory.getAuthenticator().forceLoggedInUser(request, response);

userContext.setAccount(user.getUniqueName());
userContext.setUserName(user.getLastName());

// 将 UserContext 加入到 Session
session.setAttribute(UserContext.USER_CONTEXT_KEY, userContext);
}
// 将用户存在ThreadLocal中
UserThreadLocal.set(userContext);
return super.preHandle(request, response, handler);
}
}
